As described in the background art, formaldehyde is absorbed by formaldehyde absorbing devices such as air cleaners, ventilation methods, plant sweet wormwood, and the like. In addition, the simplest means is long-time circulation of indoor air, and harmful gas in the room can be taken away and diluted. However, these methods are difficult to solve the pollution problem of indoor formaldehyde from the source.
In view of the above, the invention provides a silicon-carbon compound capable of absorbing formaldehyde and a preparation method thereof, which have the effect of solving the problem of indoor formaldehyde pollution from the source. Specifically, aldehydes and ketones can react with amines under acidic conditions to first form the nitrogen analog hemiaminal of the hemiacetal, and then gradually remove a molecule of water to form a carbon-nitrogen double bond. This functional group is called an imine, also known as schiff base. The aldol amine condensation reaction is as follows, and it can be seen that the amine reacts with the aldehyde ketone to form an imine:
some imines are prepared without any catalyst and react rapidly by simply mixing the amine with the carbonyl compound. On the basis, the invention provides a silicon-carbon compound capable of absorbing formaldehyde, a preparation method and application thereof, other amine compounds are generated through chemical reaction, formaldehyde can be rapidly absorbed, and the effect of solving the problem of indoor formaldehyde pollution from the source is achieved.
In one exemplary embodiment of the present invention, there is provided a method for preparing a formaldehyde-absorbable silicon-carbon composite, the method comprising:
mixing amino polysiloxane and active carbon, heating and stirring to obtain the amino polysiloxane; wherein the heating temperature is controlled to be 50-100 ℃, and the stirring time is controlled to be 4-12 h;

Thereby achieving uniform dispersion of the activated carbon in the aminosiloxane polymer. In addition, the addition of the activated carbon not only can play a role in adsorbing formaldehyde, but also can play a role in reinforcing the aminosiloxane polymer to form pasty liquid. The silicon-carbon compound contains rich amino groups, can be subjected to quick chemical reaction with formaldehyde on the surface of furniture and in the air, and can remove water to form carbon-nitrogen double bonds, so that the purpose of chemical formaldehyde removal is achieved.
